menacingly on the streets of the city. it took 15 minutes before the police approached and handcuffed him. the grenade launcher was a fake, a movie prop and this was an elaborate act. the imbicile was named michael turley. what is more disgusting, he didn't have the guts to do it himself. he persuaded a 16-year-old nephew to march around with the bogus rpg. an action that could have gotten the poor young teenager killed. mr. turley says he planned it because we need to pay more attention to our surroundings and be safe. he did it because he's a dangerous, attention seeking gutless little twerp. that's all for us tonight. "ac 360" starts right now. >> piers, thank you very much. 10:00 on the east coast we have breaking news tonight in the wake of the libya tragedy. late word tonight from the u.s. state department they're pulling more staffers out of the embassy in tripoli because of security concerns.
